Claims.

This invention relates to padded arms and particularly to arms padded to avoid rattle or other objectionable noises. The invention is in the nature of an improvement upon a padded arm shown in my Patent Number 2,169,321, issued August 15, 1939.

An object of the invention is to mount upon an elongated arm, a pad consisting of a. strip of yielding material folded across an end of said arm so as to extend along opposed faces, the arm being so formed as to quite positively resist shifting of the pad from its proper position.

Another object is to provide one or more points or prongs upon the terminal edge of the arm across which the pad is folded, to embed themselves in the pad and resist its lateral shifting from the arm.

These and various other objects the invention attains by the construction hereinafter described and illustrated in the accompanying drawing, wherein:

Fig. 1 is a view in side elevation of the improved padded arm.

Fig. 2 is a top plan view of the same.-

Fig. 3 is a cross-sectional view of the padded arm taken on the line 3--3 of Fig. 2.

Fig. 4 is a fragmentary longitudinal sectional View of the arm taken upon the line 4-4 of Fig. 1.

Fig. 5 is a side elevational view of a slightly modified construction.

Fig. 6 is a longitudinal sectional view taken upon the line '6-6 of Fig. 5.

Fig. 7 is a view similar to Fig. 6 disclosing a further modification.

Fig. 8 is a View similar to Fig. 6 showing a still further modification.

Fig. 9 is a cross sectional view taken on the line 99 of Fig, 8.

In these views the reference character I designates an elongated arm formed of spring sheet metal, one terminal edge of such arm being arouately reentrant as indicated at Z and thus forming acute angles of prongs 3 at the ends of said edge. Folded across the end 2 is a pad l formed by an elongated strip of yieldable and preferably somewhat resilient material such, for example, as a woven asbestos listing. This pad is slightly wider than the arm I and extends along opposite sides of such arm for a desired distance, its ends being clamped firmly to the arm by some suitable means such as the metal clip 5 which forms a band extending substantially around the pad extremities and arm. To further restrain the pad from lateral shifting on the arm it is preferred to form the latter with a small conical indentation 6 which is embedded in the pad substantially midway between the fold and extremities of the latter.

In the modified construction shown in Figs. 5 and 6, an arm I and a pad 8 are arranged in the relation first described, the arm again having a reentrant edge 9 across which the pad is folded. In this construction, however, the prongs IE1 formed at the ends of said edge are bent oppositely laterally to embed themselves in the pad.

In the modification appearing in Fig, 7 an arm H is engaged by a pad l2 in the relation first described. In this construct-ion, however, a prong l3 projects from the terminal edge of the arm across which the pad is folded, such prong thus embedding itself in the pad.

In the further modification shown by Fig. 8, an arm it is engaged by a pad 15 in the relation first described. The terminal edge of the arm across which the pad is folded is in this modification formed with a row of prongs IE, to be embedded in the pad.

In any of its described forms, the prong-s engaging the fold of the pad are highly effective to prevent any lateral shifting of the pad. The described arm is frequently subjected in use to a vibratory motion with rapidly repeated impacts tending to displace the pad on the arm, andthus detract from appearance of the installation and to expose the metal arm to contact with a stop (not shown), with resultant rattle. The present invention eliminates such possibility.

The invention is presented as including all such modifications and changes as come within the scope of the following claims:

What I claim is:

1. A padded, shock absorbing arm, comprising a length of sheet metal having one or more prongs formed at an extremity thereof, and a pad of yieldable strip material folded across said extremity and engaging said prong or prongs and having portions extending along opposite sides of the sheet metal.

2. A padded arm as set forth in claim 1, said prongs forming a row extending substantially across such extremity.

3. A padded arm as set forth in claim 1, the edge of said extremity being of a reentrant arcuate form, and each end of such edge forming one of said prongs embedded in the fold of the pad.

4. A padded arm as set forth in claim 1, said extremity of the sheet metal being formed at its ends with a pair of said prongs oppositely bent out of the plane of the sheet metal to embed themselves in the pad.

5. A padded arm as set forth in claim 1, the extremities of the sheet metal being of complementary form so that a plurality of the sheet metal elements may be cut from a strip without waste.
